| Abstract | Others have described mild or atypical myocardial infaretion as a clinical condition in which the pain is of short duration and the evidence of tissue damage is slight. It occurs in otherwise healthy individuals and is characterized by complete recovery and the absence of complications. In this study the electrocardiograms of 359 patients with myocardial infaretion were divided according to the QRS complexes; one group showing normal QRS complexes and the other showing typical Q waves. The clinical features of the patients in these two groups were compared. IN a recent article on "mild" myocardial in-farctioni, Prinzmetal, Weiner, and Bhu-yan1 describe the clinical features of this condition as follows: pain of short duration occurring in a young or middle-aged healthy man with no evidence of previous heart disease , hypertension, diabetes, or other chronic illness. Shock never occurs and evidence of tissue damage (fever, leucocytosis, sedimenta-tion rate, serum transaminase level) is either absent or slight. There is no cardiac enlargement , no congestive failure and no arrhyth-mias. In several days the patient looks and feels well. They say that normal or abnormal, the electrocardiogram rarely provides evidence concerning the severity of an infare-tion. Smith in 1951,2 when, in a series of 109 patients with myocardial infarction, they found 33 who could be classified as "slight" on clinical grounds. These consisted of absence of shock or failure, evidence of necrosis slight or absent, aiid an uncomplicated recovery in each instance. In 35 attacks the electrocar-diogram was mentioned as showing a small or absent R wave in 3 and significant Q waves inl 7. The electrocardiogram returned to nor-mnal in 14, showed improvement in 14, was unchanged in 6, and became worse in 1. Ijittmainn and Barr3 reported a total of 209 (ases of coronary disease, 11 of which were classified as atypical (small, obscure) infarets. 548 These patients gave no history of previous infaretion although 4 had a history of angina. None had shock, myocardial failure, or throm-boembolism. There were no deaths. Ten had fever exceeding 99.6 F. The white blood count varied from 7,700 to 19,200, averaging 12,200. The sedimentation rate was increased in all cases. Two patients had recurrences and progressed to typical infaretion. Cutts, Merlino, and Easton4 recently reported 79 patients with coronary type chest pain whose electrocardiogram showed inverted T waves in the chest leads without QRS abnormalities. In one third of these patients the electrocardiogram returned … |
